by the system, then carry on to click "Finish". This means that all 3 RAID
volumes configuration such as share folder etc. will all restore to the current
unit in the RAID volume "RAID".
6. In other circumstances, if the current unit contains 2 RAID volumes, then it can
be chosen from the left hand side of system backup configuration RAID volume
list which RAID volume to map to the current system.
